You can, it's just typically easier for most users to re-install than to execute the necessary steps to convert the system after the fact. If you have sufficient space then you can just create a thin pool, copy your existing file systems into it and then fix up the fstab, grub boot entries, initramfs and any other configuration that may still reference the old device names. Once you're finished you can remove the original volumes and reclaim the space for use by the thin pool.
